Outcomes are reported from this evaluation into the effectiveness of web-based alcohol screening and brief intervention (e-SBI) for reducing hazardous drinking among Māori university students in New Zealand. The study researchers emailed invitations in April 2010 to all 6697 17–24-year-old Māori university students to complete a brief web questionnaire including the Alcohol Use Disorders Identification Test (AUDIT)-C, a screening tool for hazardous and harmful drinking. Those screening positive (AUDIT-C score of ≥4) were randomised to either <10 minutes of web-based alcohol assessment and personalised feedback (intervention; n=939) or screening alone (controls; n=850). Follow-up assessments were completed at 5 months by 682 controls (80%) and 733 intervention group participants (78%). Relative to controls, participants receiving the intervention drank less often (RR 0.89), less per drinking occasion (RR 0.92), less overall (RR 0.78) and had fewer academic problems (RR 0.81).
